Solar inverter installation: best practices and common wiring errors
Five mistakes we see in practical submissions — and how to avoid burning out a customer’s inverter.

Most failed practical submissions on Ilimexa fail for the same handful of reasons. None of them are about advanced theory — they are about discipline.
1. Reversed DC polarity
Always confirm polarity with a multimeter before connecting to the charge controller. A single reversal can destroy the controller instantly.
2. Undersized cables
Long runs from panels to controller need thicker cable to keep voltage drop under 3%. Calculate it — do not guess.
Safety first
Isolate panels and batteries before touching terminals, and only do practical work under a qualified supervisor. Read our safety disclaimer before you start.
